The narcissist lacks empathy. He is, therefore, unable to meaningfully relate to other people and to truly appreciate what it is to be human. Instead, he withdraws inside, into a universe populated by avatars â simple or complex representations of parents, peers, role models, authority figures, and other members of his social milieu. There, in this twilight zone of simulacra, he develops "relationships" and maintains an on-going internal dialog with them.
The narcissist attributes his failures and mistakes to circumstances and external causes. This propensity to blame the world for one's mishaps and misfortunes is called "alloplastic defence". At the same time, the narcissist regards his successes and achievements (some of which are imaginary) as proofs of his omnipotence and omniscience. This is known in attribution theory as "defensive attribution".
Conversely, the narcissist traces other people's errors and defeats to their inherent inferiority, stupidity, and weakness. Their successes he dismisses as "being in the right place at the right time" â i.e., the outcome of luck and circumstance.
